Audi TT Quattro Performance Air Intake - Front - APR - PEX Intake System - Front Airbox - 09-15. This closed front airbox channels cool outside air while resisting engine-bay heat for consistent, responsive performance.

Constructed from high heat deflection PEX, the APR system provides an unrestricted path to the turbo and connects to the factory inlet. On the flow bench it showed a 31% CFM gain versus the factory airbox and 24% over the total stock system. A reusable pleated cotton gauze filter balances strong filtration with low restriction, sharpening throttle response, easing turbo workload, and adding a purposeful induction note. Includes mounting hardware, a billet PCV adapter, and a flex coupler for engine movement. Note: many TT applications require adapter CI100020-D; please confirm fitment and any needed adapters before ordering.
